BIOD 171 MODULE 6 EXAM | Questions and
Answers | 100% Correct (Latest Update 2025 /
2026)
1. What is the general purpose of antiretroviral medication for an
individual with HIV? ANS Antiretrovirals are intended to inhibit the life
cycle of retroviruses. By inhibiting steps in the HIV’s lifecycle,
antiretroviral medications effectively block the production of new virus
particles and lower the viral load of the patient.
2. Is a patient infected with rubella only considered infectious
when the trademark rash is visible? ANS False
3. Which subtype of Influenza is the most virulent? ANS Influenza
A
4. Describe two ways chickenpox can be spread. ANS It can be
spread through airborne droplets like coughing and sneezing. It can
also be spread by coming in direct contact with blisters of the infected
1
, person.
5. What is the main difference between lytic and temperate
phages? ANS Lytic bacteriophages are inside the host bacteria and
keep replicating until they rupture and die. Temperate phages exist in
the host bacteria, but they do not replicate and do not kill their host
cells.
6. Does viral replication occur after it attaches and enters the host
cell? ANS True
7. What disease displays secondary characteristic swelling of the
ovaries/testes and pancreas? ANS Mumps
8. What small (30nm) single-stranded, non-enveloped RNA virus
targets the CNS, causing potentially catastrophic damage to
motor neurons? ANS Polio
9. Would a drug company target hemagglutinin or neuraminidase
proteins to inhibit the release of newly produced viral particles?
Why? ANS Neuraminidase proteins are directly involved in the
budding and release of new viral particles and would be the correct
target. Hemagglutinin proteins would not be the right target because
